I spent seven and a half years going to Catholic elementry school. It wasn't hell but it wasn't heaven. Overall I think the quality of teaching was really kinda lousy, but I think that about a lot of elementry school teaching.

What I do dislike is the warped view of god and religion that I was taught in that time. Maybe it was this school, maybe it was just these teachers, but I find the Catholic world view I was raised with to be repugnant and soulless. As soon as I quit going to private school and started at a public school I found myself questioning everything I was taught. And I found it quite lacking. Catholic--->Agnostic--->Atheist was a quick transition for me. Not only was I disillusioned with the Catholic Church but also I assumed all religions were like this. It was only many years later that I started to overcome my aversion for things religious, or especially Christian.
